Identification of Hazardous/Harmful Drinking among Subcritically Injured Patients

Objectives: To examine the relationship between a saliva alcohol test (SAT) and hazardous/harmful drinking, as measured by the Alcohol Use Disorders Identification Test (AUDIT), among a sample of subcritically injured patients.
Methods: Patients ( n = 78) seeking treatment for a subcritical injury were saliva-tested for alcohol and interviewed regarding their drinking behaviors and related difficulties. Associations of SAT values with AUDIT results were determined.
Results: SAT results and hazardous/harmful drinking were not independent events (p < 0. 001). Estimates of sensitivity and specificity (using a dichotomous SAT result [≥ 4 mmol/L] to identify positive AUDIT patients) were 65. 2% and 83. 6%, respectively. SAT-positive people had significantly higher AUDIT scores than did SAT-negative individuals (p < 0. 0001). Patients experiencing assault-type injuries were much more likely to be SAT-positive than were patients incurring other types of injury. Discriminant function analysis suggests that AUDIT scores can successfully identify SAT-positive and SAT-negative patients; the analysis accounted for 42. 5% of the variance and correctly classified 84. 6% of the sample.
Conclusions: The use of an easy-to-administer, noninvasive, routine SAT, among patients presenting for a subcritical injury in a hospital ED, provides a mechanism for the identification of individuals with a history of hazardous/harmful drinking. However, since discrimination of hazardous/harmful drinking is imperfect, some caution is warranted when conducting such screening activities.     

Alcohol Use among Subcritically Injured Emergency Department Patients

Objectives: To determine the incidence of alcohol use in subcritically injured patients presenting to the ED, by using a saliva alcohol test (SAT) at ED triage during the ED initial assessment; to compare the incidence of alcohol use revealed by the SAT with documentation of alcohol use by ED nurses and emergency physicians (EPs) blinded to the SAT results; and to describe the demographics of the SAT-positive, subcritically injured population.
Methods: A blinded, prospective, observational evaluation of ED patients presenting with subcritical injuries was performed. The patients were tested for alcohol use with an SAT, and a subsequent record review was conducted for extraction of demographic data and evidence of documentation of alcohol use by ED nurses and EPs blinded to the SAT results.
Results: During the study. 791 subcritically injured patients had SATs performed. Twenty-one percent of these patients were found to be alcohol-positive by SAT. Either the ED nurse or the EP documented a clinical impression of alcohol use for 52% of the SAT-positive patients. There were higher SAT-positive rates among men (24%), victims of assault (47%), and patients arriving at night (41%).
Conclusions: While the SAT identified 21% of the subcritically injured patient population as alcohol-positive, ED nurse and EP documentation did not identify half of these alcohol-positive patients. Many of these patients may be at risk for additional injuries related to their drinking behavior.     

Analysis of Alcohol Use Clusters among Subcritically Injured Emergency Department Patients

Objectives : 1) To cluster patients according to self-reported drinking patterns using cluster analysis; 2) to externally validate clustered groups on variables related to drinking but not used in the cluster analysis; and 3) to use the clustered patients' responses to alcohol consumption questions to develop a brief screening tool emergency physicians can use to identify patients in need of referral or intervention related to potentially hazardous alcohol consumption. Methods : A self-report battery was administered to 95 subcritically injured patients. Patients also were saliva alcohol-tested upon arrival to the ED. Using the patients' self-reported quantity, frequency of alcohol consumption, and frequency of having ≥6 drinks on a drinking occasion, patients were categorized into 3 groups using cluster analysis. The 3 clusters were externally validated using injury-related variables, alcohol-related consequences, and the patients' reported readiness to change drinking. A screening tool was developed using cutoff values reported by the patients' answers to drinking pattern questions. Results : Fifty-nine patients were alcohol-negative, and 36 tested alcohol-positive (i.e., >4 mmol/L [>20 mg/ dL]) or had elevated scores on an alcohol problem screening instrument. Three distinct drinking pattern clusters were found. Clusters were validated using discriminant function analysis and multivariate analyses of variance to confirm cluster classifications. Steady and high-intensity drinkers reported more alcohol-related negative consequences, and high-intensity drinkers indicated they would consider changing their drinking. The screening tool correctly classified 97% of the patient sample into their respective clusters. Conclusions : Using the drinking pattern questions in the clustering procedure was effective for grouping injured patients into clusters that could be differentiated on other drinking-related variables. The resulting screening tool can be used in the ED setting to screen patients for further assessment and intervention. The readiness-to-change results support the assertion that the injury event provides a “teachable moment” for subcritically injured patients whose injury may be related to their alcohol consumption.     

Readiness to change problematic drinking assessed in the emergency department as a predictor of change

OBJECTIVES: The goal of this study was to determine if baseline readiness to change the drinking behavior (pre-contemplation, contemplation, preparation, and action stages) was predictive of change in drinking after unrelated emergency department (ED) visit and screening and interviewing for alcohol problems. METHODS: From August 1998 through December 2000, the Alcohol Use Disorders Identification Test (AUDIT) was administered to all consented ED patients aged 18 to 29 years. A brief motivational interviewing was provided to screen-positive patients (AUDIT score >5 of 40). Outcome at 3-month follow-up was measured as a decrease in the scores within the AUDIT domains of alcohol intake, harm, and dependency. RESULTS: Sixty percent of the screen-positive patients continued to drink at 3 months. Patients became more open to change their drinking behavior. Compared with patients in the pre-contemplation stage, those in the action stage were twice as likely to reduce their alcohol intake (OR, 2.24; 95% CI, 1.06-4.72), nearly 3 times as likely to reduce their alcohol-related harm behavior (OR, 2.80; 95% CI, 1.59-4.91), and almost 4 times more likely to decrease their dependency symptoms (OR, 3.59; 95% CI, 1.97-6.57). Compared with pre-contemplation patients, those in the contemplation stage were nearly twice as likely to reduce their alcohol-related harm (OR, 1.85; 95% CI, 1.02-3.33) and those in the preparation stage were more than twice as likely to reduce their dependency symptoms (OR, 2.20, 95% CI, 1.13-4.27). CONCLUSIONS: Stages of change at baseline appeared to be significant predictors of change in alcohol intake, harm, and dependency symptoms among young adult ED patients.     

Alcohol Use and Medical Care Utilization among Health Maintenance Organization Patients in the Emergency Department

Objective: To determine the association of an alcohol–related ED visit with medical care utilization during a two–year period surrounding the ED visit in an HMO.
Methods: A probability sample of ED patients were interviewed and underwent breath analysis in a large HMO in a Northern California county. Based on recent alcohol intake or documentation of an alcohol–related ED visit, the patients were assigned to an alcohol group ( n = 91) or a non–alcohol group ( n = 897). A 10% random sample of the health plan membership of the same county ( n = 19, 968) served as a comparison group. Utilization data were obtained from computerized files. Multiple linear regression was used to determine differences in subsequent outpatient visit rates between the alcohol and the non–alcohol groups. Logistic regression was used to compare the risks of hospitalization in the two groups.
Results: Annual outpatient visit rates were 7. 8 in the alcohol group and 8. 3 in the non–alcohol group (p = 0. 65), controlling for gender, age, and injury status, and were significantly different from the visit rate of 5. 5 for the random health plan sample (p = 0. 0001). No difference was found between the alcohol and the non–alcohol groups for risk of hospitalization; however, those in the health plan sample were less than half as likely to be hospitalized as were those in the non–alcohol group (odds ratio 0. 44, p = 0. 002).
Conclusions: No difference was found in utilization of medical services between the alcohol and the nonalcohol groups in this predominantly white, well–educated HMO ED population. However, both groups used significantly more inpatient and outpatient services than did the general HMO membership.     

Rates of At-risk Drinking among Patients Presenting to the Emergency Department with Occupational and Nonoccupational Injury

OBJECTIVES: To compare the characteristics and rates of at-risk drinking among patients presenting to the emergency department (ED) with occupational and nonoccupational injury. METHODS: Cross-sectional survey of injured patients presenting to a university hospital ED. Injured patients were prospectively identified, and consenting patients completed a survey including questions regarding quantity/frequency of alcohol use, TWEAK, CAGE, and work-relatedness of injury. Major trauma and motor-vehicle collisions were excluded. Demographic and injury information was obtained from the medical record. Patients with a TWEAK score > or =3, CAGE score > or =2, or who exceeded NIAAA quantity/frequency guidelines were defined as at-risk drinkers. Analysis utilized the Student t-test for continuous variables, and frequency and chi-square analysis for categorical variables. RESULTS: Among 3,476 enrolled patients, 766 (22%) had work injuries and 2,710 (78%) had nonwork injuries. Patients with work injuries were as likely as patients with nonwork injuries to be at-risk drinkers; 35% of patients with an occupational injury and 36% of those with a nonoccupational injury were at-risk drinkers (odds ratio = 0.96). CONCLUSIONS: Patients presenting to the ED with an occupational injury have rates of at-risk drinking similar to other injury patients, and may be an important group in which to target brief alcohol interventions.     

Acceptability of Emergency Department-based Screening and Brief Intervention for Alcohol Problems

OBJECTIVES: To adapt screening and brief intervention for alcohol problems (SBI) to a high-volume emergency department (ED) setting and evaluate its acceptability to patients. METHODS: Patients at a large public-hospital ED were screened with the Alcohol Use Disorders Identification Test (AUDIT). Screen-positive drinkers (AUDIT score >/= 6) were provided brief, on-site counseling and referral as needed. Three months later, project staff blinded to baseline measures reassessed alcohol intake, alcohol-related harm, alcohol dependence symptoms, and readiness to change. RESULTS: Of 1, 034 patients approached, 78.3% (810) consented to participate (95% CI = 75.5% to 81.2%), and 21.2% (172) screened positive (95% CI = 18.4% to 24.0%). Of 88 patients with complete intervention data, 94.3% (83) accepted an intervention (95% CI = 89.5% to 99.2%), with acceptance rates ranging from 93% to 100% across four alcohol-problem-severity levels (p = 0.7). A majority (59.0%) set goals to decrease or stop drinking (95% CI = 48.4% to 69.6%). The group recontacted (n = 23) experienced statistically significant decreases in alcohol intake, alcohol-related harm, and dependence symptoms, with measures decreasing for 68%, 52%, and 61% of the patients. Readiness to change also showed statistically significant improvement, with scores increasing for 43% of the patients. Moreover, two-thirds of the patients (15/23) reported at follow-up that SBI was a helpful part of their ED visit. CONCLUSIONS: High rates of consent and acceptance of counseling for alcohol problems by patients across a wide range of problem severity indicate that this protocol was acceptable to at-risk patients in a public-hospital ED. Improvements in alcohol-related outcome measures at follow-up were strong enough to warrant controlled studies of intervention efficacy.     

Marijuana Use and Prior Injury among Injured Problem Drinkers

OBJECTIVES: The purpose of this paper is to better understand marijuana use among injured problem drinkers in the emergency department (ED). The specific objectives are: 1) to assess the prevalence of marijuana use; 2) to identify factors associated with marijuana use; 3) to determine whether prior injury is associated with marijuana use; and 4) to determine whether marijuana-using problem drinkers want to change behaviors. METHODS: The authors conducted a post-hoc analysis on data obtained prospectively. Subjects had injury and problem drinking: either measurable alcohol level (blood alcohol concentration, BAC), report of drinking, or an Alcohol Use Disorders Identification Test (AUDIT) score of > or =8. The study was conducted on weekend nights; 3,776 injured ED patients were screened, 383 refused, 578 were enrolled, and 433 had complete data. RESULTS: Of the 433 subjects, 48.3% reported using marijuana in the three months prior. Marijuana-using problem drinkers had more hazardous drinking, higher AUDIT scores (14.0 vs. 11.4, p < 0.001), and higher risk-taking scores (12.4 vs. 10.1, p < 0.001). More used other drugs (69.7% vs. 30.3%, p < 0.001). In regression analyses, marijuana use remained an independent predictor of prior injury (OR = 2.16, 95% CI = 1.25 to 3.75), particularly prior alcohol-related (OR = 2.26, 95% CI = 1.45 to 3.53) and motor-vehicle-related (OR = 1.69, 95% CI = 1.03 to 2.79) injury. Readiness-to-change scores were similar (4.14 vs. 4.22, p = 0.21) between users and nonusers. CONCLUSIONS: Marijuana use among injured problem drinkers is prevalent. Their risk of prior injury is increased. Counseling for alcohol and injury should address marijuana use.     

A Comprehensive Statewide Analysis of Seatbelt Non-use with Injury and Hospital Admissions: New Data, Old Problem

Objectives: To investigate the association of seatbelt nonuse with injury patterns, injury severity, and in-patient hospital admission among adults presenting to emergency departments (EDs) in a statewide, population-based, sample of motor vehicle crashes.
Methods: Using data from the 2002 Crash Outcome Data Evaluation System (CODES) for Wisconsin, 23,920 occupants of motor vehicle crashes, aged 16 years or older, who were treated in an ED, were analyzed. Logistic regression was used to compare the odds ratio of having sustained an injury to specific body regions and of being admitted to an inpatient unit in unbelted individuals compared with those who were belted.
Results: Compared with belted occupants presenting to an ED, their unbelted counterparts were more likely to be male (56% vs. 40%) and to have used alcohol (17% vs. 4%). Unbelted occupants were younger (31 years vs. 38 years) and incurred higher ED charges ($681 vs. $509) than belted occupants. Additionally, unbelted occupants have a higher proportion of single-vehicle crashes, such as rollovers (44% vs. 22%), and rural crashes (56% vs. 44%). Unbelted occupants comprised 20% of study patients treated in the ED and discharged, 44% of patients treated in the ED and admitted, and 68% of patients dying in the ED. Unbelted occupants were more likely to be admitted (odds ratio [OR] = 2.6) than belted individuals and were more likely to suffer severe injuries to the head, face, thorax, abdomen, spine, upper and lower extremities (OR ranging from 1.6 to 3.9).
Conclusions: Among patients presenting to an ED after a motor vehicle crash, unbelted occupants are more likely to require inpatient admission and to have sustained a severe injury to numerous body regions than are belted occupants.     

Injury severity: role of alcohol, substance use and risk-taking

Objective: The objective of the present study was to quantify the relationship between acute alcohol consumption and injury severity. Methods: A cross‐sectional study was conducted at the Gold Coast Hospital, Gold Coast, Queensland, Australia between October 2000 and October 2001. Data were collected from a systematic sample of patients greater than 15 years of age who presented to the ED for treatment of an injury sustained less than 24 h prior to presentation. Study participants were interviewed face to face on‐site. Information obtained included: demographics details; situational variables relative to time of injury (i.e. location, activity and companions at time of injury); self‐reported alcohol consumption in the 6 and 24 h prior to time of injury; usual alcohol consumption patterns; self‐reported substance use in the 6 and 24 h prior to time of injury; and risk‐taking behaviour. Injury severity was coded from patient medical records using the New Injury Severity Score. Results: Of 789 eligible patients presenting during the study periods, 593 were interviewed (75.2%). Patients who reported drinking above low‐risk levels (odds ratio [OR] = 3.35; 95% confidence interval [CI] 1.2–9.6) or who drank beer (OR = 3.54; 95% CI 1.1–11.1) in 6 h prior to injury were significantly more likely to sustain serious than minor injury. Drinking setting and usual drinking patterns were not significantly associated with injury severity, either in crude analyses, or after adjusting for relevant variables. Conclusion: The results of the present study support the conclusion that among injured patients who presented for treatment at a large metropolitan ED, although acute alcohol consumption does not appear to be associated with minor or moderate injury, there is some evidence to suggest that acute alcohol consumption is associated with serious injury.     

Alcohol Abuse/Dependence in Motor Vehicle Crash Victims Presenting to the Emergency Department

Objective: 1) To determine the prevalence of current alcohol abuse/alcohol dependence (AA/AD) among the full injury range of ED motor vehicle crash (MVC) patients; and 2) compare AA/AD and non-AA/AD patient characteristics.
Methods: This was a prospective cohort study using a stratified random sample of MVC patients aged ≥18 years presenting to a university hospital and university-affiliated community hospital ED from May 1, 1992, to August 30, 1994. A diagnosis of current AA/AD was based on the alcohol section of the Diagnostic Interview Survey (DIS). Other measurements included the presence of blood alcohol (BAC +), Injury Severity Score (ISS-85), occupant status (driver/passenger), age, gender, seat belt use, culpability for crash, and ED disposition (admitted vs released). A weighted prevalence was determined; subgroups were compared using t-tests, χ². 2-factor analysis, and logistic regression modeling; α = 0.05.
Results: 1,161 patients were studied. The weighted prevalence of current AA/AD was 22.5%; 53% of these patients were released from the ED. Almost 45% of the patients with current AA/AD were BAC —. When controlling for BAC and AA/AD, greater injury severity and culpability were associated with a BAC +, but not with current AA/AD.
Conclusion: Almost 23% of ED MVC patients have current AA/AD; BAC testing does not accurately identify these patients. Intervention strategies must be directed to both admitted and released patients.     

Alcohol Use among Injured Patients Aged 12 to 18 Years

Objective : To examine the scope of alcohol use among a population of injured adolescents.
Methods : A convenience sample of injured patients aged 12–18 years seen at a pediatric ED was tested for the presence of alcohol. Injured patients seen within 6 hours of their injuries were asked to submit urine samples for testing using reagent strips. Data were collected from the patient, out-of-hospital emergency care personnel, and parents regarding the circumstances of the injury.
Results : Of the 243 injured patients who were tested during an 8-month period, 231 were included in the final analysis. Ninety patients (39%) were alcohol-positive. The mean age of the alcohol-positive group was 16.0 ± 1.64 years, compared with 15.3 ± 1.8 years for the alcohol-negative group (p < 0.003). There was no significant difference between the 2 groups based on race, gender, or injury characteristics. A positive urine alcohol test was found for 18 (33%) of the motor vehicle crash victims, 9 (38%) of the motor vehicle drivers, 10 (37%) of the patients who attempted suicide, and 49 (44%) of the assault victims.
Conclusions : A substantial percentage of injured adolescent patients were alcohol-positive. The authors recommend the use of alcohol screening when treating injured adolescents.     

Attribution of injury to alcohol involvement in young adults seriously injured in alcohol-related motor vehicle crashes.

BACKGROUND: Approximately 40% of all traffic fatalities are associated with the use of alcohol. Hospitalization for serious injury after a motor vehicle crash related to use of alcohol may be an opportunity to change drinking behaviors in non-alcohol-dependent drinkers, thereby reducing the risk for future disability and death. OBJECTIVES: To determine the degree to which non-alcohol-dependent adults aged 18 to 45 years with alcohol-related vehicular trauma attributed their injury to use of alcohol. METHODS: During hospitalization, 132 subjects involved in alcohol-related motor vehicle crashes were interviewed. The interviews included the question, "To what extent do you believe your alcohol consumption was responsible for this injury?" Responses were measured on a 7-point scale ranging from 1 (not at all) to 7 (totally). RESULTS: In response to the question about attribution of injury to alcohol, 37.8% of subjects responded "not at all," 24.3 responded "somewhat," and 37.9% responded "mostly" or "totally." Spearman rank correlation between attribution of injury to alcohol involvement and blood alcohol content at admission was r = 0.440 (P < .001). CONCLUSIONS: More than 60% of patients injured in alcohol-related motor vehicle crashes attributed their injury partly or totally to use of alcohol. When alcohol-free, hospitalized patients with higher blood levels of alcohol on admission were more likely than those with lower levels to attribute their injury to alcohol. Hospitalization for a motor vehicle crash related to use of alcohol provides an opportunity for interventions to decrease drinking.     

The Significance of Out-of-hospital Hypotension in Blunt Trauma Patients

Objective: To determine the significance of a low out-of-hospital systolic blood pressure (SBP) reading in blunt trauma patients who have a normal SBP upon ED arrival.
Methods: A retrospective case-control study compared admitted blunt trauma patients who were hypotensive (SBP ≤90 mm Hg) in the field and normotensive in the ED (group 1) with those who were normotensive both in the field and in the ED (group 2). The groups were compared for mortality, intensive care unit (ICU) admission, injury severity scale (ISS) score, need for transfusion in the ED, incidence of intra-abdominal injury, and incidence of pelvic or femur fracture.
Results: Each group consisted of 52 patients. The groups were similar with respect to age, gender, and initial ED SBP. The group 1 patients had a higher mortality (10 vs 1, p = 0.008), a higher number of ICU admissions (28 vs 12, p = 0.001), more pelvic or femur fractures (16 vs 7, p = 0.03), and a higher ISS score (19.0 vs 10.5, p = 0.01). Although not significant, group 1 also had higher incidences of intra-abdominal injury (10 vs 3, p = 0.07) and transfusion (8 vs 2, p = 0.09).
Conclusion: The injured patients who were hypotensive in the out-of-hospital setting but normotensive upon ED arrival were more severely injured and had more potential for blood loss than were the patients who were normotensive both in the out-of-hospital setting and in the ED. Out-of-hospital hypotension may be a clinical predictor of severe injury, even in the face of normal ED SBP. Prospective studies are indicated to validate this hypothesis.     

Violence and Substance Use among an Injured Emergency Department Population

OBJECTIVES: This study evaluated a sample of emergency department (ED) patients for history of violence and substance abuse. METHODS: Injured patients (n = 320) completed questionnaires (14% refusal rate) during a visit to a Level 1 urban ED after an acute injury. Specific questions were asked regarding whether the injury was related to acute violence (AV), whether there was past-year violence history (VH), including violence victimization and perpetration in both partner and nonpartner relationships, as well as any substance use in the past month and any substance-related consequences in the past year. RESULTS: Fourteen percent of the participants presented with an AV-related injury, and 53% reported VH. Most AV patients (89%) reported VH. No significant differences were found between the participants with AV and VH in demographic, substance use, or substance-related consequences. The AV and VH groups were combined (V), with analyses comparing these participants with those without AV and VH. Men were significantly more likely than women to report V (odds ratio = 2.0). V was significantly related to substance use and substance-related consequences. For example, in comparison with the participants reporting no alcohol or drug use, those reporting illicit drug use were 6.2 times as likely to report V, and those drinking any alcohol only were 2.0 times as likely to report V. CONCLUSIONS: A large percentage of injured patients in this urban ED experienced violence in the past year. Alcohol and illicit drugs appear to be concomitant with violence.     

Drinking context and cause of injury: Emergency department studies from 22 countries

Background: It is estimated that up to a third of injuries requiring emergency department (ED) admission are alcohol-related. While injuries that are alcohol-related are unsurprising to ED staff, less is understood about the precursors to the injury event.

Methods: Using data from representative ED injury patients in 22 countries, we examined associations between context of injury (private or public), cause of injury (fall or trip, being stuck/cut/or burned and violence) and alcohol use. Alcohol-related policy data were also obtained from each study locale.

Results: Injuries were similarly reported in private (54%) and public settings (46%), while cause of injury was most often due to falls (39%) or being struck/cut or burned (38%). Violence-related injuries were reported by approximately 1 in 5 patients (23%). Increased odds of drinking prior to the injury event was associated with injury due to violence in private settings but not public venues. Similarly, patients from regions with fewer restrictive alcohol policies were more likely to report drinking prior to an injury event and have elevated violence-related injuries in private settings.

Conclusion: Understanding the cause and context of injury and alcohol use are important components to evaluation and development of alcohol policies.     

Psychosocial Difficulties and Emergency Department Use

Objective: To determine whether psychosocial difficulties are more prevalent among ambulatory patients using the ED for nonemergent complaints as compared with ambulatory patients having emergent complaints.
Methods: A survey of noncritical ED patients was performed using anonymous questionnaires addressing psychosocial difficulties: psychiatric illness, educational level, homelessness, alcohol and/or drug dependency (CAGE and DAST surveys), and depression (DSM-III criteria). Three independent physicians ranked each patient's chief complaint as either emergent or appropriate for primary care. The majority ranking was used to determine whether the complaint was emergent. Groups with and without specific psychosocial difficulties were compared for their proportion of emergent vs primary care complaints.
Results: Of 700 patients, 367 (52%) met criteria for ≥1 psychosocial difficulty [acute psychosis—36 (5%), illiteracy—139 (20%), homelessness—45 (6%), alcohol dependency—111 (16%), drug dependency—66 (9%), and depression—130 (19%)]. There were 379 (54%) ED visits considered emergent. Patient groups with vs without ≥ psychosocial difficulty had similar rates of emergent visits (58% vs 50%, p = 0.04). Emergent visit rates also were similar for subgroups with vs without specific psychosocial difficulties: psychosis (56% vs 54%, p = 1.00), illiteracy (58% vs 53%, p = 0.89), homelessness (62% vs 54%, p = 0.33), alcohol dependency (62% vs 53%, p = 0.08), drug dependency (59% vs 54%, p = 0.47), or depression (58% vs 53%, p = 0.42).
Conclusion: Psychosocial difficulties are common among ED patients; however, emergent complaints are just as common in these patients as they are in those without psychosocial difficulties.     

Effects of Parental Presence during Children's Venipuncture

Objective: To determine whether parental presence during venipuncture (VP) altered self-reported distress of the child, the parent, or the health professional (HP) performing VP.
Methods: During nine consecutive months, 130 nonconsecutive 8–18-year-old children having VP in an urban pediatric ED were prospectively randomized into two groups of 65 patients each. Before VP, every child, parent, and HP completed a questionnaire developed to measure epidemiologic variables believed to influence distress during VP. The patients were randomized to have either a parent present or both parents absent during VP. The patients, the parents, and the HPs privately self-reported their distress during VP on a visual analog scale (VAS). Statistical significance was determined by the Mann-Whitney U (rank-sum) test.
Results: In the parent-present group, distress scores were lower for the parent (p < 0.01) and for the child (p < 0.04) than they were in the parents-absent group. The HP performing VP had no difference in distress scores with and without parental presence (p < 0.55).
Conclusions: Parents and children having VP have less distress with parental presence. Health professional distress is not affected by parental presence.     

Association of Out-of-hospital Criteria with Need for Hospital Admission

Objective: To validate high-risk historical and physiologic out-of-hospital criteria as predictors of the need for hospitalization following ED evaluation.
Methods: Consecutive patients entered into the Suffolk County advanced life support system were enrolled. Previously proposed historical and physiologic "high-risk" criteria for hospitalization were prospectively collected. Criteria were associated with the need for hospital admission following ED evaluation.
Results: 1,238 patients were enrolled; 391 were released from an ED after transport. Most patients (843/1,238; 68%) were admitted to a hospital; and four died in the ED. Factors associated with an increased likelihood of admission or death among the transported patients were: bradycardia (90% admitted, p < 0.02); hypotension (80%, p < 0.03); hypertension (89%, p < 0.03); and age > 55 years (81%, p < 0.0001). Unresponsiveness and other abnormal vital signs were not associated with admission on univariate analysis. Logistic regression analysis identified two other factors associated with admission or death: tachycardia (72%, admitted, p < 0.01) and head injury (78% admitted. p < 0.001).
Conclusions: Abnormal pulse or blood pressure, head injury, and age > 55 years are associated with patients' requiring hospital admission after accessing the emergency medical services system. These criteria may aid the design of out-of-hospital refusal-of-care policies.     

The Urban Epidemiology of Recurrent Injury: Beyond Age, Race, and Gender Stereotypes

Objectives: To profile all patients presenting to an urban ED with any injury, and to determine whether the rate of subsequent injury treated in the ED varied by demographic and E-code (external mechanism of injury) category. The hypothesis that young black males were disproportionately at risk for re-injury was addressed.
Methods: A cohort of consecutive patients presenting to an urban ED with any injury between January 1, 1991, and November 31, 1992, were followed prospectively for 1 year from their index visit dates. Any repeat ED visits due to injury were sought. The mean number of injury visits per year (the total number of ED injury visits for each patient divided by 1 year) was computed for the overall population and by race, age, gender, and E-code.
Results: The sample consisted of 34,378 patients who made 44,813 visits to the ED for injury. Of these patients, 22% had a repeat injury in 1 year, with a cohort mean of 1.30 injury visits per year. This mean did not vary appreciably by race (black 1.33, white 1.27), age (1–17 yr, 1.21; 18–24 yr, 1.32; 25–64 yr, 1.34; >65 yr, 1.23), gender (males 1.33, females 1.27), or E-code category. Having a prior injury visit in the preceding year was the best predictor of future injury (mean repeat visit rate = 2.08).
Conclusions: When examining patients presenting with any injury to an urban ED, the mean numbers of injury visits are remarkably similar across demographic and E-code categories. Although there are factors that place patients at risk for recurrent injury, those factors are not demographic—all patients presenting to an ED with injury should be considered at risk for re-injury.
